In this paper, we propose a new weaving trajectory algorithm for the are welding of a articulated manipulator. The algorithm uses the theory of Bezier spline. We make a comparison between the conventional algorithms using Catmull-Rom curve and the new algorithms using Bezier spline. The proposed algorithm has been evaluated based on the MATLAB environment in order to illustrate its good performance. Through simulations, the proposed algorithm can result in high-speed and flexible weaving trajectory planning so that it s trajectory cannot penetrate into a base metal compared to the conventional algorithm using Catmull-Rom curve.

Where is the Oriental martial arts going in these days? Can it be separated with sports or physical education to get its own region? To get a solution from these questions, there are three parts of studies of the possible trends on Korean martial arts such as the actual conditions on educating coach of martial arts, the research about thesis of martial arts, and the actual conditions of related journals. For the conclusion, the following five solutions could be shown. At first, there should be a general modification on processing of educating the martial arts coach. 1. Expanding the items of martial arts can raise the level of coach's educating quality based on the curriculum, the contents, and the variety programs. 2. Martial arts sports, ordinary martial arts, and traditional martial arts must be unifiable and simple to develope its problems. 3. the importance of traditional martial arts and the qualified test of its coach must have a mutual preservation and maintenance through being related with each other between martial arts' each items. Second, it's necessary to train the martial arts with required elements of the recognition, the theory, the existence and the philosophy. Third, it's necessary to take shape of pyramidical structure through the long term policy of training martial arts. Forth, variety events of martial arts should be held regularly from the government. At last, it's necessary to expand the martial arts region and make variety activities from related academies or institutes.

This paper presents an economic model to determine producer's tolerance factor of a quality characteristic with 100% screening inspection on the assumptions of continuous quadratic loss function and linear inspection cost. A solution procedure for the optimum tolerance is developed and illustrated with a numerical example. Taguchi's tolerance determining procedure have been analyzed in the framework of western statistical quality control although Taguchi has derived tolerances with the consideration of quadratic loss function and deterministic quality characteristic.

Adult polycystic kidney disease(APKD) usually accompanies with renal and extrarenal manifestations and liver cysts are present in aproximately 30% of patients with APKD. Kidney cysts often accompany with hemorrhage, rupture, infection, however, liver cysts are usually asymptomatic and do not impair liver function. Rare complication of liver cysts in patient with APKD include portal hypertension with bleeding esophageal varices and hepatic failure with encephalopathy. But, in APKD patient, infection of liver cysts without infection of renal cysts is extremely rare. We report a case of infected liver cyst in a patient with APKD who has complained generalized abdominal pain and high fever which was confirmed by ultrasound and aspiration. The patient was treated successfully with repeated aspiration and systemic antibiotics.

According to the system of the oriental traditional science, everything has to be harmony and interact with one another. The fundamental notions of the traditional natural philosophy are "do(doctrine)", "taegeuk(the great absolute)", "yin-yang," "five primary substance", "four events", and "eight signs for divination". Taegeuk, especially, explains the formation and the death of all things in the universe through circulation of yin-yang, and shows the balance of nature and universe. Yin-yang, relative ideas produces four events, and four events also is divided into the eight signs for divination. 'four events', 'eight signs for divination' like 'yin-yang' indicates the cycle of nature. The essential notions of the traditional science are not different from those of modern chemistry. Taegeuk which is the origin of all things in the universe means the situation of harmony and balance through ceaseless circulation and connotes dynamic equilibrium on neutralization that chemical reaction get to. A number of opponent concepts such as acid-base, oxidation-reduction, atomic nucleus-electron are given an explanation by ying-yang(the positive and negative) that reaches Taegeuk through chemical bonding or reaction over simple antagonistic relationship. 'Yin-yang', 'four-events', 'eight signs for divination' do not imply a substance or a phenomenon in itself but the properties of them. That is why it is possible to see into various chemical concepts like a relative strength of acid-base, groups of periodic table with traditional scientific philosophy. We have regretfully neglected studies in traditional science. It is time to perform the concrete work connecting theory of traditional science with that of modern science for advisable appreciating of traditional science. Moreover, It is necessary to do research and development of educational programs or teaching-learning materials using the traditional science properly. 동양 과학 철학이나 자연 철학은 태극,음양오행,사상팔괘를 이용해 우주 만물의 운동과 자연의 순환을 설명하는데 있어 그 학문적 우수성을 부인할 수 없으나 현대의 화학식이나 수식이 현상을 미시적 관점에서 구체적으로 설명할 수 있는 것과는 달리 전통 과학이론은 거시적 관점에서 그 전체적 흐름만을 나타낸다는 한계를 가지고 있다. 그럼에도 불구하고 태극,음양오행 그리고 사상팔괘론을 중심으로 한 전통 과학 이론은 현대인들에게 과학에 대한 새로운 시각을 제공함으로써 무분별하고 비윤리적인 과학 기술 활용으로 인한 전 지구적인 문제들을 해결하는데 있어 핵심적인 역할을 수행함은 물론 오늘날의 한국 과학이 한 걸음더 전진하는데 이바지 할 수 있을 것이다. 그러므로 서구 중심의 기존의 과학문명에만 머무를 것이 아니라 동양의 전통 과학 철학을 연구하여 민족의 과학 체계를 수립하고 과학의 토착화를 이루어야 한다. 이를 성공적으로 수행하기 위해서는 전통 과학과 현대 과학 사이에 다리를 놓는 구체적인 작업이 본격적으로 진행되어야 한다. 기본적인 화학 개념들을 전통 과학적 관점에서 재해석 하는 것은 물론이고 더 나아가 전통 과학의 이론을 이용하여 화학 반응 과정을 구체적으로 설명하려는 시도가 필요할 것이다.

This study was designed to examine the mianserin effects on the negative symptoms of chronic schizophrenia. The chronic schizophrenics(N=14) diagnosed by DSM-Ⅲ-R, who were treated at the Catholic University St. Mary Hospital from March 1, 1993 to August 31, 1995, were divided into two groups. One group was composed of 7 patients who were treated with a single classical antipsychotic agent(monotherapy group, MG), and another was composed of 7 patients treated with combined medications(combined therapy group, CG), including classical antipsychotics plus fixed dose of mianserin 30 ㎎/day at bed time. Symptoms were evaluated by BPRS(Brief Psychiatric Rating Scale) and PANSS(Positive and Negatve Syndome Scale) biweekly for 6 weeks, i.e., total 4 times(at baseline, at 2 weeks, at 4 weeks, and at 6 weeks). The results were as follows : 1) Assessed by PANSS, the negative symptoms of CG were statistically significantly improved more than those of MG at 2 weeks, at 4 weeks, and at 6 weeks. 2) Assessed by PANSS, the positive symptoms of CG were not statistically different from those of MG. In both of CG and MG, there was no difference of the positive symptoms across time intervals. 3) Assessed by PANSS, the total symptoms of CG were statistically significantly improved more than those of MG at 2 weeks, at 4 weeks, and at 6 weeks. But, assessed by BPRS, the total symptoms of CG were not statistically different from those of MG. 4) Assessed by PANSS, the general psychopathology symptoms of CG were not statistically different from those of MG. In CG, the general psychopathology stmptoms at 6 weeks were statistically significantly improved more than those of baseline. In summary, mianserin, when combined with classical antipsychotic agent, appears to be effective in diminishing negative symptoms of chronic schizophrenic patients. However, it did not influence positive symptoms.

아황산가스가 흰쥐 허파조직내 Laminin 활서에 미치는 영향에 대한 면역조직학적 연구

Sulfur dioxide (SO_2), a kind of air pollutant, causes harmful damage to human body. In particular, inhalation of sulfoxide dioxide has been demonstrated to result in the injury to the upper respiratory duct. However, mechanisms by which SO_2 affects these tissues remain to be clarified. In the present study, to investigate the mechanism of SO_2 effects, the influence of SO_2 exposure was examined in terms of the injury of lung and the expression pattern of laminin in the basal lamina. The basal lamina is an important tissue for the regulation of internal respiration by composing of air-blood barrier. Sprague-Dawley rats repetitively exposed to a mixture of O_2 gas and SO_2 gas (250 ppm) for 30 minutes a day were sacrificed to observe the distribution of laminin in the alveolar septum as well as the morphological alteration of alveoli using immunohistological methods. The resutls we observed were as follows: 1. Alveoli from SO_2-exposed rats (for 5 days) were strongly stained with anti-laminin antibody, suggesting laminin expressed at the high level, at week 1 to 3 upon exposure to SO_2 2. At week 1 to 3 after exposure of rats to SO_2, alveolar septa were collapsed, leading to the reduction of alveolar volume along with morphological changes to irregular shapes. 3. At week 4 to 6 after exposure of rats to SO_2, alveoli were weakly stained with anti-laminin antibody, suggesting laminin expression was decreased during this period. 4. Rats sacrificed at week 7 upon exposure to SO_2 exhibited the expansion of new alveoli and the expression of laminin was partially recovered up to the intermediate level. Taken together, these results demonstrate that the expression of laminin was enhanced in the early phase, followed by downregulation in the late phase. Moreover, lung injury and resolution were correlated with the level of laminin. Thus, these results suggest that SO_2 suppresses the expression of laminin, which may be associated with the neo-generation of lung tissue.
